4.22 Ghostlights and Instances

nebulafox

So I have a scene back from 4.15 (I upgraded directly from 4.15 to 4.22) that I need to update the lights for. Most of the lights in the scene are all ghost lights, and I had to pare back a lot of the things in the set to be able to fit two characters. At some point I turned many of the lights into instances as it saved time.

After updating the main lightsources with the new ghostlight method (advanced iray properties -> iray visible to primary rays + iray ghost light factor), I've found that the instances I already had DON'T inherit this, and now just float as glowing orbs.

Is there nothing I can do without just making new instances or just duplicating the lights? Not a major loss if I have too, but certainly annoying.

Advanced Iray Node Properties will not be derived from the ghost lights to Instances.... You have to add Adv. Iray Properties to the Instances and set them up in the same way, with same property values.

Trying to add it to the instances says it's already ON the instances, but there's no option to turn off Iray Visible to Primary Rays on the instances themselves. I can simply just makes duplicates of the light, but it's certainly a bit annoying this is the way it is.

That means you ever added advanced Iray node properties with old script of Create Advanced Iray Node Properties. Since the latest GL / Create Advanced Iray Node Properties script are newly-invented, you have to "rework" on the Instances...
